    The first passives used a soft foam like covering and most bubbled, some very badly. The second passives had a hard plastic like front exterior but they made up the weight by putting a bolt in the back of the Styrofoam. I've used both in my SDA1 signatures (came with foam front passives) and actually felt the hard front was the better passive. It could of been expectation bias who knows :D :D :D

    My .02 I wouldn't worry about using these in any that take a 12" passive.

    Interesting. My 1Cs have the exact same looking passive, but is labeled SW120. It was a transitional 1C model however.
